* network: DHCPv6 Assign delegated prefix to LAN interfaceSusant Sahani2020-05-291-0/+1
| | | | | | | | | In DHCPv6-PD environment, where WAN interface requests IPv6 via DHCPv6, receives the address as well as delegated prefixes, with LAN interfaces serving those delegated prefixes in their router advertisement messages. The LAN interfaces on the router themselves do not have the IPv6 addresses assigned by networkd from the prefix it serves on that interface. Now this patch enables it.

|\ | | | | networkd: subnet id support for ipv6 prefix delegation
| * networkd: Add support for setting a preferred subnet id for IPv6 PD leasesAndreas Rammhold2020-05-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows users to configure a subnet id that should be used instead of automatically (sequentially) assigned subnets. The previous attempt had the downside that the subnet id would not be the same between networkd restarts. In some setups it is desirable to have predictable subnet ids across restarts of services and systems. The code for the assignment had to be broken up into two pieces. One of them is the old (sequential) assignment of prefixes and the other is the new assignment based on configured subnet ids. The new assignment code has to be executed first and has to be taken into account when (later on) allocating the "old" subnets from the same pool. Instead of having one iteration through the links we are now trying to allocate a prefix for every link on every delegated prefix, unless they received an assignment in a previous iteration.

* network: Fix split in `SendOption=` on client and serverDavid Wood2020-03-191-0/+2
| | | | | | | | | | | | | | | | | When specifying `DHCPv4.SendOption=`, it is used by systemd-networkd to set the value of that option within the DHCP request that is sent out. This differs to setting `DHCPServer.SendOption=`, which will place all the options together as suboptions into the vendor-specific information (code 43) option. This commit adds two new config options, `DHCPv4.SendVendorOption=` and `DHCPServer.SendVendorOption=`. These both have the behaviour of the old `DHCPServer.SendOption=` flag, and set the value of the suboption in the vendor-specific information option. The behaviour of `DHCPServer.SendOption=` is then changed to reflect that of `DHCPv4.SendOption=`. It will set the value of the corresponding option in the DHCP request.
